Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76866, here are decompositions:
- 19 + 76847 = 76866
- 29 + 76837 = 76866
- 37 + 76829 = 76866
- 47 + 76819 = 76866
- 89 + 76777 = 76866
- 109 + 76757 = 76866
- 113 + 76753 = 76866
- 149 + 76717 = 76866
Showing the first eight; more decompositions exist.
